Who can take part

• Participant must be ≥ 12 years of age at the time of signing the informed consent/assent
• Weight ≥ 35 kg
• Bronchiectasis diagnosed by a physician and confirmed by CT demonstrating abnormal bronchial dilation in ≥ 1 lobe. Note: A historical CT scan within the past 5 years is acceptable. If not available, a CT scan should be conducted at screening to confirm eligibility
• Participants who are receiving appropriate standard of care therapy per local guidelines and have a documented history of ≥ 2 moderate exacerbations or ≥ 1 severe exacerbation in the preceding 12 months requiring antibiotics
• Participants who are clinically stable and free from an exacerbation of bronchiectasis for 4 weeks prior to randomization
• Participants with pre- or post-bronchodilator FEV1 ≥ 25% predicted value at screening
• Presence of positive (PCR or culture) PsA in an airway sample at least once in the last 24 months prior to screening
• Presence of culture positive PsA in sputum at least within 5 weeks of randomization. Participants who have previously received PsA eradication therapy, as determined appropriate by their treating provider, but remain colonized with PsA are eligible for the study. Participants who experience an exacerbation during the screening period and receive antibiotic therapy remain eligible for the study if the presence of culture-positive PsA is confirmed prior to randomization
• Capable of giving signed informed consent/assent which includes compliance with the requirements and restrictions listed in the ICF and in this protocol
